Sayang, cramping + bleeding dalam early pregnancy mmg boleh jadi normal, tapi considering you have both symptoms, jangan delay, please go to the doctor or emergency room today to check everything is okay, especially since the scan yesterday didn't show much yet. Better safe than sorry at this stage, and they can give you peace of mind. A few of my mum friends had similar scares early on and turned out fine after proper check-up, but some needed closer monitoring, so doctor needs to see you in person and possibly rescan to be sure. Don't wait lah, go now
